Then the other factor will be the size and pitch of the prop. Your speed and performance will vary. The water and wind conditions affect the performance of the boat on every outing. There are so many variables, length of the boat will affect it more than weight, machiens instance, a 14 foot boat will move pounds faster than a 12 foot boat, streeam flotation.

Shape of the hull, V or flat bottom, width, alI these affect your speed. I am guessing based on my 20 hp on a 14' boat with 3 adults that you will probably make somewhere around 20 mph.

Block the apropos with the round circle inside 2 cheeks written to lift a flip of the wire .

Important: If the boat takes t down and t up respectively to travel same downstream and upstream distance, then we the following relation:. Question 4: A boat takes 6 hours to go downstream and comes back upstream in 12 hours.

Find the ratio of the speed of the boat and the speed of the stream. Question 5: A man rows 10 km upstream and back again to the starting point in 55 min. If the speed of the stream is 2 kmph, then find the speed of the boat in still water.

It takes 15 hr to reach its destination and return back if river has no flow. For the same journey it takes 16 hr if river is flowing. Find speed of flow of river. Your email address will not be published. Skip to content Boats and Streams is an essential topic for many competitive exams. Boats and Streams � Terminologies: Stream: It implies that the water in the river is moving or flowing. The second factor is the length of the boat.

It's the second rule of thumb: the longer the boat, the faster it goes. Each sailboat has a maximum hull Average Speed Of Boat And Stream 0.25 speed, which it can't exceed in theory. The hull speed is determined by the length of the boat. Please note: the maximum hull speed isn't the average sailing speed. It's the upper limit in theory - read on to learn more.

The third and perhaps most obvious factor of course is wind direction and speed. If you plan a large voyage, for example, an ocean passage, make sure to check the dominant wind and direction for your time of year.

You want to make Average Speed Of Boat And Stream Designs sure to have as much downwind as you can get, and a favorable current as well. This is why most sailors choose to go eastward instead of westward when sailing the world. If you want to know why going eastward is smart, I encourage you to read my previous article on sailing around the world here. So imagine you need to get to dock in time. It's 50 miles away.

You need to arrive at hours. It's currently hours. Would be handy to know at what speed you need to sail to make it in time. Great, we have a good general idea of what to expect from our trustworthy vessels.

If you want to go deeper, you can try to calculate the maximum hull speed of your own boat. Calculating the maximum speed is actually very simple. Now is the time to get out your calculator. You calculate the maximum hull speed HS by taking the length in feet lwl , get the square root, and multiplying it by 1.

A displacement hull has a maximum hull speed. Hull speed is a theoretical speed that tells us what the maximum efficient speed is. Everything above that speed costs a lot more energy. If you power your boat by engine, you can exceed the speed by pushing the hull over your own bow wave this requires a lot of horsepowers though, and it isn't good for your engine.

If you're sailing instead, you can exceed your hull speed with the help of the weather. Let's call these surfing conditions sounds good.

This might happen to you when you're sailing downwind and the current pushes you forward simultaneously. This helps you to overtake your own bow wave. If this happens, the wavelength gets longer than the hull length: the water can't get out of the way fast enough. As a result, the boat starts to plane, increasing water resistance at the front.

Congratulations: you're surfing on your own bow wave. The increase in speed won't be mind blowing however about 1 knot. The truth is: a displacement hull is bound to its speed. It just costs to much energy to propel it through the water. It's made to cut, not steamroll the water. Because of this, they can cover quite a bit of distance. What distance are we actually able to cover with conservative speeds?

The average sailboat covers a distance of roughly nautical miles NM , at a speed of around 4. This equals miles or km.

Most sailboats cover anywhere between NM per day. Example 2: A boat travels equal distance upstream and downstream.

What is the speed of the current? Example 3: A boat is rowed down a river 28 km in 4 hours and up a river 12 km in 6 hours. Find the speed of the boat and the river. Solution: Downstream speed is ,.

Speed of current Downstream�Upstream speed. When the river is running at 1. How far is the place? A man rows a certain distance downstream in X hours and returns the same distance in Y hours. Example 5: Vikas can row a certain distance downstream in 6 hours and return the same distance in 9 hours. Example 6: Two ferries start at the same time from opposite sides of a river, travelling across the water on routes at right angles to the shores.
